Abstract

The invention discloses a control system and method for a hybrid universal charger, a control circuit for a universal electric vehicle charger comprises a voltage stabilizing circuit, a main power AC / DC circuit, a detection circuit, a feedback circuit and a control circuit, the control circuit is connected with a battery, the voltage stabilizing circuit outputs voltage, the detection circuit detects voltage and current of the battery and transmits the voltage and current to the control circuit, and the control circuit outputs charging pulse signals through the feedback circuit. The control circuit for the universal electric vehicle charger provided by the invention not only can charge a lead-acid battery, but also can charge a lithium battery, is suitable for charging the battery of any electric vehicle, and can protect the battery at the same time.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a control method and system for a hybrid universal electric vehicle charger. Background technique [0002] The current electric vehicle chargers on the market are generally only designed for the battery type used in electric vehicles, and can only be limited to the use of charging the battery of the electric vehicle. At present, the batteries used in general electric vehicles are basically divided into two categories: one is lead-acid batteries and the other is lithium batteries. That is, the batteries used in electric vehicles are lead-acid batteries, and only special lead-acid battery chargers can be used. The batteries used in electric vehicles are lithium batteries, and only special lithium battery chargers can be used. Ordinary users will not charge the battery of the electric vehicle by mistake with the same type of battery charger due to lack of common sense of some batt...
